Green spaces as ecological capital for cities
Untapped potential lies dormant between buildings. Urban green spaces can make a decisive contribution to climate adaptation and biodiversity. Landscape architecture must be more than just a specialist discipline. It should take the lead in systemic urban development.
Studies show that in cities such as Bern, there are dozens of hectares of what is known as “distance green”. Lawns with no function that are merely mowed. These areas are a previously unused asset. They could store rainwater, cool the urban climate and create habitats for diverse species. Instead of being viewed in isolation, they need to be understood as an interconnected ecosystem.
Planning beyond plot boundaries
Climate change and biodiversity do not stop at plot boundaries. Nevertheless, the competence of property owners is limited to their plots. To realize the potential of urban green spaces for climate resilience and biodiversity, we need political guidelines, cooperative action and new professions that professionally maintain and develop urban green spaces. A systemic approach to urban development is essential.
Landscape architecture with a claim to leadership
Architecture shapes urban development with grand gestures, but the robustness and sustainability of urban systems lies in open spaces. This is where landscape architecture has its strength. It can create resilient, ecological structures with minimal resources. This requires more self-confidence in the discipline and a willingness to take a leading role in urban development.
Education for the future
In order to meet the growing demand for landscape architects, new training paths are needed. A Bachelor’s degree course at Bern University of Applied Sciences could close this gap and test innovative teaching models. Central content would be systemic approaches that combine ecological, social and spatial factors and translate them into sustainable concepts.
The green space between buildings is not superfluous. It is the ecological capital of the future. Those who see it as an integral part of urban planning will create resilient, liveable cities that can withstand the challenges of climate and biodiversity.
